To all whom it may concern:

Be 'it known that We,GEo zeE E. PURPLE and ALBERT B. BEACH, citizens of the United States, residing at Chicago, in the county of" belts'andthe like. Its main objects are to provide couplings of-this class whichshall be strong and durable, which can be easily and quickly ap' lied to belt ends withoutspecial tools, ant which will admit of readily disconnecting and connecting the ends of a 'belt'without' detaching the members of the .couplingtherefrom, and generally to 'iin 'prove the construction and operation and increase the convenience of such couplings. 1

It consists in certain novel features of construction and n the peculiar arrangement and combinations of parts as. hereinafter particularly. described and pointed. out in the claims.

In the accompanying drawing like char.- acters designate the same or similar parts in the several figures. I

I

I The coupling in its several modified forms is composed of twon'iain members which are l alike andare struck 'or cut primarily in a fiat form.

member a is formed with two sets of prongs b and cgand with. intermediate hinge loops or bearings d, the prongs of each set and the hinge loops at each end being connected by erly locating the members square across the ends of a" belt when they are placed thereon with one or more inwardly bent transverse shoulders j", forming stops or gages, as f shown in Figs. 2 and t, for the ends of the belt to abut against. These steps also'serve to prevent the ends of the beltfroni entering points or ends of the prongs their shanksand the. connecting strips (2, while the shanks with the connecting. strips are primarily bent outward, diverging sufagainst theshoulders- .f. In this form the ready for attachment to belts, which is read- .ily accomplished by driving thepointed ends of the prongs through the belthnd-clenching then; in or upon it, as shownin Figs. '1. and 2. This does not require special tools, but may be done with an ordinary hammer or similar tool. The connecting strips e and the shanks of the prongs are preferably curved slightly inward between the shoulders f and theinturned points or ends, so that they 'will be, embedded in or closely hug the faces of the belt when. the-pointed 1 ends are driven throughit and clenched. In this form of coupling the hinge loops (1 are centrally widened orexpanded, the openingsbetween them being widened at the ends and of less width between the ends than the cen- .l tral portions of the loops, so that the loops from sheet metal,

I are bent-in wardly at approximately right angles to cross strips e. To insure and facilitate pro 7d and attached thereto, each member is formed ficiently to readily permit of the. insertion of a belt end between the opposing points coupling members are supplied to the. trade 1 and 6, but'a hin of one member will interlock 'with'those of the-other-member when the pivot pin is reoved, thus preventing l-the separation of the members except by a movement of one 'm'ember first toward the other and then in a direction transverse to the planeof the belt.

, When the members of the 'coupling have beenattachedto'the ends of a belt'as above F 'i'.ated,-tl18' lOOpS of one member are inserted rise through the enlarged ends. of the" openings between the loops of the, other member, and a pin 9 is'then' passed through the';loop:s' of both members, pivotally con- -'1'!ect1ng'-them',' as 'shownin Figsll and 2.- To hold. the Din'in'place, the terminal loop at f; ;one end "of. each-member is formed with an or projection h,' which is bent inwardly fojvere end of thepin' Thepr'ongs b of .iwhm alternate with the prongs c n 3 opposite side neeted atone end'onlyv by a cross stripe,- the v shorter: prongs ',b being separate continua-q In this case the: stops tions of the loops.
